The method that contains your code must have at least the first 
parameter 'self'::

   def pdfwrite(self):
     R = self.REQUEST.RESPONSE
     R.setHeader('content-type', 'application/rtf')
     R.setHeader('content-length', str(len(data)))
     R.write(data)

It's a way of getting access to context.
